Description
Technical field
The utility model relates to a kind of reduction valve auxiliary device, particularly a kind of reduction valve thermal insulation apparatus.
Background technique
Existing reduction valve heat-supplying mode is mainly electric heating or the mode of covering and heat insulating, this technology is that heating tape is wrapped on reduction valve wall, by temp controller, control the temperature of electric-heating belt, can reach and prevent icing object, but voltage instability or power failure cannot adopt electrical tracing technology; The long-time electrical tracing that uses, can cause the aging or resistance wire of isolation layer to occur that short circuit produces spark, and the possibility causing the accident is very large.
Model utility content
The purpose of this utility model is, provides a kind of electrical tracing the reduction valve thermal insulation apparatus mixed with hot water heating.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of reduction valve thermal insulation apparatus, comprises hot-water supply device, heat conductive tube, heating electric silk, heat-transfer device; Described heat conductive tube is communicated with hot-water supply device, and heat-transfer device one end is located in heat conductive tube, and the other end is fixed in reduction valve wall; Described heating electric filament winding is on reduction valve wall, and heating electric silk and heat-transfer device connecting part are provided with non-conductive layer.
One of preferred version of the present utility model, reduction valve body wall inwall is provided with circular protrusion, forms cavity in projection.
One of preferred version of the present utility model, it is volute that heat-transfer device is located at heat conductive tube inner, heat-conducting plate is U-shaped pipe at cavity end, two ends of U-shaped pipe are connected with volute two ends, U-shaped pipe is provided with one-way valve, volute and U-shaped pipe form an annular sealed hollow cavity, have heat-conducting liquid in hollow cavity.
One of preferred version of the present utility model, three groups of heat-transfer devices of radially direct on reduction valve wall.
One of preferred version of the present utility model, heat-transfer device imports the hot water in hot-water supply device in cavity.
One of preferred version of the present utility model, the triangular in shape or hemisphere in projection transverse section.
One of preferred version of the present utility model, hot-water supply device EXIT POINT position is than at least two meters of the vertical height of reduction valve.
The utility model advantage is, use above structure, heating electric silk heats reduction valve wall, heat-transfer device imports the hot water of hot-water supply device or hot water heat in reduction valve wall, setting by artificial or Mechanically programm can complete the heating of heating electric silk and hot water heating alternately or heating jointly, overcome the problem that under problem that the heating of electricity silk can not long-time heating or voltage instability, power-off condition, electricity thread cannot heat.
Existing reduction valve body wall inwall is plane, and main considering compression rock gas enters in reduction valve by pipeline rapidly from airtight gas cylinder, and gas volume can expand rapidly, and the planar inner wall of reduction valve is conducive to volume expansion, can not hinder gas flow; Adopt hot water heating reduction valve wall, its heat exchange efficiency is lower, to hinder the basic reason that ability technician adopts technique, if establish interlayer on reduction valve inwall, utilize interlayer to carry out heat exchange, although can improve the heat exchange efficiency of hot water heating, reduction valve can reduce because interlayer thickening can make the efficiency of heating surface of heating electric silk.On reduction valve inwall, be provided with projection, although can affect gas flowing in reduction valve, but can heat and hot water heating by compatible electricity silk, by the setting of projection, more reasonably arranged wall temperature field in reduction valve, not only increased the heat absorption area of gas, gas is flowed in reduction valve (there will be 0.2 degree left because heat absorption area increases near the gas temperature of valve mural margin and the temperature of reduction valve motive body apart from shortening in a short period of time, the right temperature difference, the obstruction that adds upper process, on reduction valve wall limit, formed a kind of hot gas cushion steam body band that is similar to, make center gas flow out the speed of reduction valve faster than the speed on reduction valve wall limit)
Hot-water supply device EXIT POINT position, than at least two meters of the vertical height of reduction valve, can utilize the gravity pressure of water to realize directed water supply.
